Reducing SOx and NOx emissions and treating ballast water may increase energy use in shipping, depending on solution applied.
Future fuels for shipping need to have a significant lower carbon footprint: ~80-90 % reduction
Production and availability are uncertain.
Moderate to extensive speed reduction (20-50% reduction) is technically feasible
50% reduction will require commercial acceptance and a restructuring of the logistics system.
Currently known and mature energy efficiency measures can reduce emission per ship by 20-30 %, dependent on ship type.

Barriers to implementation
10
• Technical uncertainty – maturity, reduction effect, system integration
• Financial and economic constraints- cost of implementation, access to capital, cost of operation
• Risk – safety and reliability, complexity
• Behavioural barriers- lack of information and awareness
Energy efficiency
• Price, production and availability
• Risk – safety and reliability, complexity
• Bunkering infrastructure
• Different types and qualities of fuels
• Engine compatibility issues
• Ship-shore compatibility issues
• Sustainability of fuels (lifecycle emissions) – and documentation hereof
Alternative fuels
• Complex global transport chains with high value cargo
• Cargo owners have low knowledge and acceptance of speed reduction impacts
• Not allowed due to charter party clauses
• Financial and economic constraints – uncertain business case
• More ships are needed, and current ships are not efficient at low speeds
